## ABSTRACT

This chapter discusses the concept of probability. The focus is not with the mathe-

matical aspects of probability but rather with the meaning of probability, although

this will sometimes use mathematics. Ultimately, the subject of probability is ap-

plied in the real world and so a clear understanding is required of what probability

statements mean. It is necessary to be able to explain exactly what is meant by the

probability of an event is, for example, 0.735. This proves to be much harder than one might think at first. Arguments about

the meaning of probability have persisted almost since the earliest development of

the concept. These disagreements have lead to substantial division in the statistical

community and contribute to the lack of a firm foundation for a statistical theory that

is generally accepted. This chapter is, in part, a survey of the different schools of

thought concerning the meaning of probability.
